'lhis inventionrelatesto Windshield heaters for motor vehicles and has for the primary object, the'provision of a device of the alcove stated character which will eficiently a collect heated air from the engine of the motor vehicle and deliver said air against the outer face ot the windshield to melt ice or snovv which may adhere thereto, thus maintaining the Windshield tree ot' snow or ice permit the operator of the vehicle to have clear vision,

Another object ot this invention is the oil a Windshield heater including a collecting device and heat conveying so associated vvith each other and the vehicle that the tall Width of the Windshield receive heated air or the heat collecting element may he removed and the heat con- "toying means closed against the reception or heated air consequently rendering thedevice inoperative which is desirable in snnoniers driving A. "hirther object ot this invention is the provision of a windshield heater of the above s ated character which will he simple, durahle and and "which may he manta? d and sold at comparatively lovv 11 these and other ohjects in view, this i in certain novel features rnction con'ihination and arran eparts he hereinafter more in y .ihed and claimed In reference is to he had to the follow a cription and accompanying drawing in llignre l is a fragmentary vertical sectional illustrating Windshield heater conatrncted accordance with my invention and applied to a motor vehicle, I

l ignre E2; is a vertical horizontal sectional illnstratinp the same llli nre 3 is izront elevation partly in section illustrating the heat collecting element, Figure i is a perspective view illustrat'in the heat collecting element.

Figure 5 is a tragmentary plan view illustrating the heat collecting element removed from the vehicle a complete understanding of my hi a and the heat conveying means closed against the reception oil heat from the motor compartment of the vehicle.

Referring in detail to the drawing, the numeral 1 indicates the cowl of a motor vehicle body having associated therewith the Windshield 2*and partition 3 closing the engine compartment 4.- troni the driving cornpartinent 5. The engine is illustrated at 6 and during the operation thereof, the tan 7 employed for cooling the radiator, drives air rearvvardly from the engine and said air hecoines heated to high temperature and in" order to collect this air and deliver the same against the Windshield 2, my invention is era- Y played.

The partition 3% is provided with an open ing in rear oi the engine 6 and an attach ng plate 8 is detachahly secured to the on 3 over said opening hy fasteners 9 ano. formed integral therewith substantially tunnel shaped collecting element 10 the per portion of which projects over the en vvith the rear wall oi the collecting element extending downwardly between the engine and the partition Nipples 11 are tor ed integral with the attaching plate 8 and are in communication with the interior of the tun l shaped collecting element and project i the compartment t? by tray of the ope the partition 3 extend into conch The top vvall ot the covvl l in advance Windshield 2 is provided with elongate to receive the discharge ends 13 ot the co duits 12, The conduits l3 flare irons their intahe ends toward their discharge ends and have hinged to their discharge ends covers it Which are normally urged into closed positionhy springs it and are operated by handles 15 jonrnalled to the instrument hoard it of the vehicle, The inner ends'oif the handles l5 are journalled in the conduits 12 as shovvn at l? and are provided with 1 angularly extending portions 18 'pivoa connected to the covers by links 19 so that on rotating the handles in one direction covers will he swung upwardly into open position for the purpose of permitting heated air collected by the element 10 to pass through the conduits and to be discharged against the outer face at the vvind shieldand adjacent the lower edge thereof so that said heated air will contact with substantially the entire surface of the windshield for the purpose of melting snow and ice that may adhere thereto. The rotation of the handles 15 in an opposite direction will bring the covers into a position for closing the conduits preventing the heated air from the engine from striking the windshield.

The forward ends of the conduits are formed integral with an attaching plate 20 secured to the partition 3 over the opening thereof by the fasteners 9 for the purpose 0 preventing the conduits from becoming accidentally disconnected from the nipples 11.

During summer driving when the necessity of such a device is not needed, the collecting element 10 may be removed and the plate 21 placed over the opening in the partition 3 by being secured to the latter by the fasteners 9 to prevent the heated air within the engine compartment from entering Stud conduits.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of my invention, as claimed.

Having thus described my invention, what I claim is:

In combination with a motor vehicle having a partition between the engine compartment and the drivers compartment and provided with an opening, an attaching plate overlying said opening, fasteners detachably securing the plates to the partition, a collecting element carried by said plate and arranged in rear of the engine, nipples carried by the plate and in communication with the collecting element and extending through the opening, a second attaching plate receiving the nipples and removably secured to the partition by said fasteners and overlying the opening, flaring conduits formed on said second attaching plate and receiving the nipples extending through the cowl of the Vehicle in advance of the windshield, and a control means for said conduits.

In testimony whereof I aflix my signature.
